ALBERTZYDROUILLARD, on WInDsom-ONTARIO, CADA- Y Appneation mea April 19,1923.' sena-rnb. 633,09111I- Be it known that' I; 'nnnnr DRoUILnARn, asubject ofvthe'King.I o'f England', residing at yV'indsor, inthe county o fLEsseXg Province ofOntario,y Canada', have 'invented certain new and useful Improvements in* Closet Ventilat'ors, of"'whi'ch thel following' isl` a j specification, referenced beinghad vtherein to theaccompanying drawings'. p

A This invention relatesto devices forfo'rcibly extracting the. air from waterv closet bowls, and its .objectis' to pjr'ovidea device which'is simple in construction and cheapV` tio manufacture and'whichmay be' very jquiclr'l'y andV readily installed' upon. water closetsas commonly constructed, without any change y I y j bowl of themsualconsbruetionwhich infthe;

whatever inthe closet. y

A further Objectis to provide a devicefor the purposewhich may be readily installed within the 'space between a water closetbowl and the adjacent wall,- by an'unslilled" person, the construction and 'arrangement of the-device being sucli'as to readily' it within the space and avoid the. littingsusually c 4-proyided in connectionwith water closets. A1 further Objectis t`o provide afdev'ice which isefficient in operation' and isfL compa-ct" in j construction so as to take up but little' space and is adapted to beso positioned a'sto'be f t@inconspicuous when in operative position.

It'isfalso an'object tosc construct and arrangetlie suction fan and its'casingv as to* y Y t'lie'appllcatio'n off the fdevice embodying.,the "(invention; to a"water closet bowl as; corni-nsure against thel fouling, of the' fanv by material which may accidentally get" into they inlet of the casing` and to further conon sol that a` removable'L cover maybe provided for'theY casing which may be' readily rremloved without disturbing the' motor' orI suction fan, whereby access maybe' hadtoV they interior of thecasing and the fan may be readily repairedwitliout dismo'unting the entire device. A further objectV is to provide certain otherl'new and useful features.` yin the `construction andv arrangement' of' parts5 all as hereinafter more fully described. W'ith the above and other ends 1n view, lthefinvention consists i-n the mattersbhereinafterset forth. and more particularlyYV pointed out in theV appended claims,v refer- Figure A'1l 1s afside l ele-vationI of. a-water c illustra-nivel off-theL invention applied` there*- to and in operative position thereon; M

y dijiyen? f' electr-'icf "orff vother' powery *may* be en'i'ploy'ed`` Thismotor isZ directly secured to4 and suspended from the bottom ofa' suit-` t ably shape'df sheet? metall casing v11,A within which casingisa suction fan l2i-'ofan old andwell known f'0rm,f -saidfan being inounted directly"y upon? the projecting end-w13` of the motor' shaft', said motor shaft, projectn mgl-upwardly ythrough-ithe'jbottcrnr of the casing 11'1 'v V'ithf* 'the fansecuredljdirectly to said inwardly 'projecting end;` "Thejbody yor cena width to fit between the hinges 6 and will be of a thickness to permit of its insertion between the cover 5 and the upper surface of the rim of the bowl. The circular casing 11 is also formed with an air outlet pipe 16 arranged tangential to the circular casing and of a vertical depth equal to that of the casing.

As the motor is secured and suspended directly from the fan casing, the device may be installed as a unit without brackets or other supporting means for the motor, the casing and its outlet and inlet arms, or pipes, spanning the space between the closet bowl and the adjacent wall of the room so that the device will be rigidly supported in place by the bowl and wall without the necessity for other supports or fastening means. Due 'to the tangential arrangement of the inlet and outlet pipes, the fan casing is offset laterally of the inlet, and therefore the devi-ce may be readily installed without disturbing the usual flush pipe connections, and the outlet 16 of the casing maybe extended through the wall or connected to any suitable flue therein.

As Vshown in F ig. 5, the casing is provided with a cover 17 having a down turned ange and formed with extensions integral with the cover, which form covers for the inlet and outletl pipes leading to and from the casing. Suitable fastening means, such as screws 18 passing through the down turned flange of the cover, are provided to secure the cover in place, and as the motor is suspended directly from the bottom of the casing and the fan 12 is made fast to the inwardly projecting end of the motor shaft, said fan and motor are supported entirely independent of the cover 17, which may therefore be readily removed without disturbing the other parts, for the purpose of gaining access to the interior of the casing and its inlet and outlet pipes.

The suction fan 12, as shown in Fig. 3, is positioned within the lower part of the casing 11, and the blades of this fan are of lesser width than the depth of the casing, so that a considerable free open space 19 is provided between the upper edge of the fan blades and the cover. The inlet pipe 14 opens into this space 19 above the horizontal plane of the upper edge of the fan and therefore any material which may accidently arrears@ get into the open end of the inlet pipe, may readily pass through the casing above the fan and out through the outlet 16, without becoming entangled in the fan.

is the casing and its inlet and outlet pipes may be very readily formed from sheet metal, and as this casing forms the support for the motor, thus eliminating the necessity for brackets or other supports, the device Amay be very cheaply constructed, and as it may be installed by an unskilled person, its cost to the user is at the minimum. Obviously, any suitable motor may be used for driving the suction fan, and other changes may be made within the scope of the appended claims, in the construction and arrangement of parts, to provide for the exigencies of the particular installation, without departing from the spirit of the invention, and such changes are contemplated.

Having thus fully described my invention, what I claim is 1. A water closet ventilator comprising a casing which is circular in plan view and is formed with integral inlet and outlet pipes, said pipes extending laterally from the casing in opposite directions and tangentially from opposite sides of the casing, said inlet pipe being widened toward its inlet end in horizontal section and tapered toward its inlet end in vertical section, said linlet pipe being of lesser vertical width than the vertical depth of the casing, a motor secured to the bottom wall of the casing and having a shaft extending through said wall into the casing, and a horizontally disposed suction fan secured to the inner end of the motor shaft.

Q. A water closet ventilator as characterized in claim 1 and wherein the vertical width of the suction fan .is less than the vertical depth of the casing to provide a free space between the upper side of the fan and the top of the casing, which space forms a continuation of the inlet to the casing, whereby a free passage for material entering the inlet is provided across and over the fan.

3. A water closet ventilator comprising a sheet metal casing of substantially circular form in plan view, said casing being provided with integrally formed inlet and outlet passages, said outlet passage extending tangentially from one side of the casing and being of a vertical depth equal to that of the casing, and said inlet passage extending laterally from the side of the casing opposite to that from which the outlet extends, said inlet passage being tapered in vertical cross-section from the casing toward its inlet end and being broadened in horizontal section from said casing toward its inlet end, said inlet passage being of lesser vertical width than the vertical depth of the casing and opening into the casing adjacent the llO upper side thereof, a motor secured to the bottom of the casing and having a shaft eX- tending through said bottom at the axis thereof, and a suction fan secured to the in- 5 wardly projecting end of the motor shaft, with the horizontal plane of the upper side of the fan below the horizontal plane of the lower side of the inlet to the casing, whereby a space forming a Continuation of the inlet to the casing is provided within the cas- 10 ing above the fan between said fan and the top of the easing. f

In testimony whereof I ax my signature in presence of two witnesses.
